Kev sib dhos cov ntsiab lus thiab cov cai rau cov kab loj loj flanges

Kev sib dhos cov ntsiab lus thiab cov cai rau cov kab loj loj flanges

1. Thaum sib sau cov mating flange, lub qhov ntsia hlau ntawm lub flange rear yuav tsum tau ua raws li cov bolt qhov sib txuas ntawm lub flange ruaj khov thiab sib npaug rau cov flange ruaj khov. Qhov sib txawv tsis ntau tshaj 1.5 thiab tsis ntau tshaj 2 hli.

2. Siv lub 90-degree square los xyuas thiab kho qhov chaw ntawm lub flange loj ntawm sab laug thiab sab xis. Tom qab tsim nyog, ua qhov chaw vuam ntawm lub ntsiab lus thib peb thiab plaub kom tiav qhov chaw vuam thiab kho ntawm flange.

3. Thaum siv flanges rau cov khoom siv los yog valve fittings, ua tib zoo saib seb lub flanges ntawm cov khoom qub lossis valve fittings zoo ib yam nrog cov flanges siv hauv cov kav dej.

4. Thaum sib sau ua ke lub tiaj tiaj vuam flange, cov yeeb nkab kawg yuav tsum tau muab tso rau hauv 2/3 ntawm lub puab txoj kab uas hla ntawm flange, thiab tom qab ntawd lub flange yuav tsum tau welded rau cov yeeb nkab. Yog hais tias lub flange yog kab rov tav, txoj hauj lwm flange yuav tsum tau welded los ntawm sab saum toj, thiab tom qab ntawd kuaj thiab kho nrog lub kaum sab xis ntawm 90-degree los ntawm ntau cov lus qhia, kom lub sealing nto yog perpendicular mus rau hauv nruab nrab kab. pipeline, thiab qhov chaw welded hauv qab yam tsis muaj qhov yuam kev.

5. Ua ntej sib sau cov kab loj loj flange, ntxuav lub flange nto, tshwj xeeb tshaj yog cov sealing nto.

Tom qab stainless hlau flange yeeb nkab fittings yog welded, lub hardened flange yog loj dua thiab yooj yim rau tawg. Yog tias tib hom chromium stainless hlau electrodes (G202, G207) yog siv rau vuam, nws yog ib qho tsim nyog yuav tsum tau preheat ntau tshaj 300 tom qab vuam, thiab ua kom txias txias ntawm li 700. Yog tias qhov vuam tsis tuaj yeem kho cua sov tom qab vuam, stainless hlau. flange yeeb nkab vuam rods (A107, A207) yuav tsum tau siv.

Rau stainless hlau flanges, txhawm rau txhim kho corrosion kuj thiab weldability, tsim nyog stabilizing ntsiab Ti, Nb, Mo, thiab lwm yam. Lub vuam kev ua tau zoo ntawm stainless hlau flanges yog zoo dua li ntawm chrome stainless hlau flanges. Thaum siv tib hom chromium stainless hlau flange electrode (G302, G307), nws yuav tsum tau preheated saum 200, thiab tempered ib ncig ntawm 800 tom qab vuam. Yog tias qhov vuam tsis tuaj yeem kho cua sov, stainless hlau flange yeeb nkab vuam rods (A107, A207) yuav tsum tau siv.

Stainless hlau flange yeeb nkab fittings thiab taub qab vuam flange electrodes muaj corrosion kuj zoo thiab oxidation kuj, thiab yog dav siv nyob rau hauv tshuaj, chiv, roj av, kev kho mob machinery manufacturing thiab lwm yam lag luam.
